Physical fitness and depressive symptoms during army basic combat training

Area of Science:

• Military Medicine
• Psychological Health
• Exercise Science

Background:

• Mental health issues contribute significantly to attrition in basic combat training (BCT).
• Civilian studies indicate physical fitness benefits psychological well-being.
• The link between physical fitness and psychological adjustment in BCT remains under-explored.

Purpose of the Study:

• To investigate the association between physical fitness and depressive symptoms among soldiers undergoing BCT.
• To determine if higher physical fitness predicts lower levels of depressive symptoms during military training.

Main Methods:

• Prospective study of 300 soldiers during BCT.
• Assessed physical fitness using the Army Physical Fitness Test (APFT) at baseline.
• Measured depressive symptoms using the Center for Epidemiologic Studies Depression scale at baseline and end-of-cycle.

Main Results:

• Soldiers in the high fitness category (APFT score ≥180) had 60% lower odds of reporting depressive symptoms.
• This association remained significant after adjusting for demographics, sleep, confidence, and Army identification.
• Low fitness was associated with increased odds of depressive symptoms.

Conclusions:

• Soldier physical fitness is associated with psychological adjustment during BCT.
• Enhancing physical fitness prior to BCT may improve mental health outcomes.
• Findings support the integration of fitness programs to support soldier well-being.
